Fox Sports 1, which will launch Saturday with Sprint Cup practice and the Camping World Truck Series race from Michigan among its opening-day programming, still does not have agreements in place for some of the biggest cable and satellite providers.

DirecTV, Time Warner Cable and Bright House Networks confirmed Tuesday that they had no agreements in place to carry Fox Sports 1. Dish also is among those that have not announced any agreement to carry Fox Sports 1, which is being converted from the Speed channel.

Speed is in nearly 86 million homes but many of those would be affected if no agreement is finalized by the network, which has NASCAR, baseball, college sports and UFC among its main programming.

According to the SportsBusiness Journal, Speed costs about 23 cents each month per subscriber, and Fox is looking to increase that to 80 cents per month.

NASCAR has repeatedly refused to comment on the situation and the possibility of fans being left in the dark. ESPN has the Sprint Cup race telecast Sunday, so that will not be affected.

“For many operators, Fox Sports 1 will launch in the same channel location now occupied by Speed,” Fox Sports said in a statement. “We hope that all major cable, satellite and telephone video services will offer Fox Sports 1 at the time of its August launch this month, giving it wide distribution.”

MIS President Roger Curtis expressed confidence that agreements will be reached.

“We know our friends from Fox are working very closely with the cable providers to make sure the new Fox Sports 1 is available to as many fans as possible,” Curtis said. “And we’re confident they’ll work out all the contracts.”

NASCAR programming will be some of the first programming the network is scheduled to deliver. Originating from MIS, Fox Sports 1 will air NASCAR Live at 8 a.m. Saturday followed by Sprint Cup practice at 8:30 a.m., truck qualifying at 9:30 a.m., Cup practice at 11 a.m., the truck pre-race show at noon and the race at 12:30 p.m.

On Sunday, NASCAR RaceDay is scheduled for 10 a.m. on Fox Sports 1 and then NASCAR Victory Lane is set for 7 p.m.

Camping World Truck Series practice is scheduled for Wednesday from Bristol with the race later that night also on FS1.

Fox also is launching Fox Sports 2 this weekend in place of Fuel. That conversion is expected to happen seamlessly as the subscriber fees for that network are not expected to change, according to SBJ.

The changes also have provided angst for fans in Canada, where Fox Sports 1 won’t yet be available. The Speed channel that remains on Canadian television providers will carry the Fox Sports 1 coverage from Michigan.
